Fix Double-Root Problem

[oferbr]

Some types of sentences produce errors in eu.excitementproject.eop.lap.biu.uima.ae.parser.StanfordDependenciesParserAE, as the same sentence gets more than one root in the dependency parse tree. The problem is probably in the underlying EasyFirstClient or any of its related classes.

Currently the aforementioned class and also eu.excitementproject.eop.lap.biu.uima.CasTreeConverter handle this bug specifically, by actively ignoring it. This could lead to mistakes (sentences not being processed, parts of trees removed, etc). Once this bug is fixed, these classes must be reverted to their normal behavior.

Example sentences/paragraphs causing the error:

• "The evidence is strong for the effectiveness of behavioral treatments in ADHD.[102] It is recommended first line in those who have mild symptoms and in preschool-aged children.[103] Psychological therapies used include psychoeducational input, behavior therapy, cognitive behavioral therapy (CBT), interpersonal psychotherapy (IPT), family therapy, school-based interventions, social skills training, parent management training,[14] neurofeedback,[104] and outdoor activities.[105] Parent training and education have been found to have short-term benefits.[106] There is a deficiency of good research on the effectiveness of family therapy for ADHD, but the evidence that exists shows that it is comparable in effectiveness to treatment as usual in the community and is superior to medication placebo.[107] Several ADHD specific support groups exist as informational sources and to help families cope with challenges associated with dealing with ADHD."
